of Ufologists launched a campaign called "Freedom of Information Now!" with the goal of pressuring the government to release information on UFO sightings. On 20 May 2005, Gevaerd led a delegation of ufologists who met with Brazilian Air Force officials in Brasília headed by Brigadier Telles Ribeiro, chief of the Air Force's Center for Public Communications. In an interview after the meeting, Gevaerd said his group had been shown information on three specific cases: the testimony of the head of Varig, Nagib Ayub, on a UFO seen in the airspace in Rio Grande do Sul in 1954, testimony from pilots who pursued 21 UFOs flying over São Paulo, São José dos Campos and Rio de Janeiro in May 1986, and a Brazilian Air Force investigation of UFOs held in 1977 in Pará, by Colonel Uyrange Hollanda, who died in 1997. According to Hollanda, "we detected at least nine forms of objects. Probes, flying saucer-shaped spaceships... All reports were sent by the 1st COMAR to Brasilia." At a 2007 seminar on UFOs in Chile, he disclosed "Operation Plate", a highly secret UFO research project conducted by the Brazilian Air Force. In August 2008 Gevaerd stated that the government has plenty of information that UFOs enter Brazilian air space every day, but refuses to publish it. Discussing the campaign for release of government information, at a September 2008 meeting of UFO enthusiasts he stated, "We are being visited by many civilizations from other planets. I have a feeling that we will soon have an answer to the questions we are all seeking." In April 2009, Gevaerd described the declassification of documents that have always been declared TOP SECRET as a historic event. He said no country had gone so far in the disclosure of information on UFOs. In September 2009, Gevaerd announced receipt of a significant new set of UFO-related government documents, some of which had been secret for 80 years. The documents included fresh details of UFO reports from the night of 19 May 1986, when 21 spherical objects, which according to military sources were 100 feet in diameter, were detected by radar and sighted by civilian pilots and literally blocked the main airports in Brazil including São Paulo and Rio de Janeiro. However, Gevaerd said in an interview that tapes of the interception operations from that event had been destroyed. In March 2010 Gevaerd discussed the downgrading of UFO documents
